I can't tell what's going on. Can you take a picture a little further out?

#

which pin are you trying to remove?

stoic spindle
#

RST

#

4th pin from the top on the outside

#

just pull the plastic off the bottom pins with pliers. It doesn't serve a lot of function, does it?

#

the normal way to solder this is to put the black plastic between the kb2040 and the carrier board, and solder the top of the kb2040 and the bottom of the carrier board, not the top of the carrier board

#

then put your soldering iron on the top of the reset pin and push downwards, waiting to melt the solderalong the pin. You should be able to push the pin down to be flush with the top of the kb2040. Or, after you take the plastic off, just grab the RST pin with pliers, and heat from the top. Pull and as the solder melts you should be able to pull it out

#

take a picture of the "flush cutter" you mentioned

#

you should be able to cut the plastic with a knife. You only need to cut it on either side of the RST pin and then grab what's left, and pull it up with needle-nose pliers

Alright I dislodged most of the plastic

#

ok, now try heating and pushing down on the pin. You can put the board on two raised thingsso there is space for the pin to be pushed down, so you can push straight down. Or just heat the top and grab from the bttom. Do you have pliers to do that?

#

or heat from the side, the heat will have less distance to travel

stoic spindle
#

Yeah I tried heating it for a while and pushing down while it was suspended and I just could not get it to move. I do have some pliers, but I'm afraid of the pin breaking and it making the job harder.

#

Here's a photo of the bottom of it

#

with as much plastic as I could get off

hallow tusk
#

the pin will not break if you pull straight. It will come out easily when the solder melts. don't try to force it

#

did you try the pushing?

stoic spindle
#

Yes I was pushing with the iron

hallow tusk
#

did you see both blobs of solder melt?

stoic spindle
#

I did

#

Oh

#

well

#

I wasn't able to see

#

Sadly my house's lighting is very poor

#

I'll actually go see if I can get a better light in here

hallow tusk
#

YES

stoic spindle
#

Yes I did see both blobs of solder melt

hallow tusk
#

are the holes really tight? You could try pushing from the bottom instead of the top

stoic spindle
#

yeah still same result

#

it's not budging

#

I think I might stop it here for tonight and I'll revisit this tomorrow morning

#

It'd be a lot easier if I could do it there, but this is a high school and my club room is really the only one with the equipment for this.

#

But, school has been cancelled for a few days now

#

because of the snow in New England

hallow tusk
#

i am here too

#

Newton, MA

#

neat

hallow tusk
#

good night - think about whether there's any other place in the school, like a metal shop, with possible tools. Ask you teacher if you think they are handy mechanically.

stoic spindle
#

Will do, thanks for all the help and good night

#

I ended up getting some help from my club advisor after school today and it's been removed!
